What Is Disp=shr ? |
|
Answer» DISP=SHR permits old data SETS to be SHARED. SHR is identical to OLD except that several jobs may read the dataset concurrently in multiprogramming environments. SHR must be used only for input data sets; USE OLD or MOD if data set is modified. Sharing data set is necessary because public LIBRARIES like SYS1.LINKLIB or the subroutine libraries should be available to every JOB in the system. DISP=SHR permits old data sets to be shared.
